摘要
提出了一种网格环境下基于PDA的交通信息发布系统。该系统以强大的交通信息网格为支撑,在PDA嵌入式平台上为用户提供交通信息,尤其是动态信息的获取、可视化、分析、输出等服务。该系统为PDA用户提供基于网络技术的实时交通路况、动态路径决策等传统导航设备所缺乏的实时动态信息。从系统总体架构、实现的关键技术、与后台网格的交互过程等多方面介绍了该移动导航系统的设计与实现。
The paper presents a traffic information demonstration system implemented on PDA in the environment of traffic information grid. Supported by powerful background grid services. This system provides the ultimate users with services such as fetching, displaying, analyzing and outputting traffic information, especially dynamic and real-time traffic information. Integrating modern grid technology, this system can offer dynamic and real-time information services, such as real time traffic status and dynamic shortest path scheme, which overcome the limitation of traditional navigation systems. This paper introduces the system＇s software architecture, the key technologies of implementation and the communication mechanism with background grid platform.
